Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes. Our overall effective tax rate for the three months ended June 30, 2014 was 26.9% compared to 25.0% for the corresponding period of 2013. For the six months ended June 30, 2014, our effective tax rate was 27.1%, compared to 15.2% for the corresponding period of 2013. Excluding the reinstatement in 2013 of the 2012 research and development tax credit of approximately $500,000, which was recorded in the first quarter of 2013, our effective tax rate would have been 24.8% for the six months ended June 30, 2013. The effective income tax rates for the three and six-month periods ended June 30, 2014, when compared to the corresponding periods of 2013, were higher, primarily as a result of a higher mix of earnings from our U.S. operations, which are taxed at a higher rate than our foreign operations. The difference between the income tax expense reported and amounts computed by applying the statutory federal rate of 35% to pretax income was principally due to the effect of foreign and state income taxes, tax credits and discrete tax items.
